LX Zeus v 3.0 25.6.2014
- 7 -
1 System description
The system consists of a minimum of two units. One of them is a gliding computer and another unit is a
57 mm vario. The vario unit is also available as an 80 mm option. The gliding computer has a sunshine
readable and anti-reflective 5.5 inch colour display and a high power Linux running computing device. The
vario is a standalone unit and has its electronics based on high precision digital sensors and transducers.
The connection between vario and computer unit is via LX system bus. System extensions (second seat
unit, remote control, compass ....) are also possible after connecting the LX system bus solution. All
connections are plug and play, what means no specialists are required to install the system.
1.1 Screen size options
LX Zeus comes in five different screen size variants, which makes it possible to install the LX Zeus
system into practically any instrument panel. The complete electronics and also all functions are the same
for all variants. The only difference is, that 2.8 and 4.3 variants uses a 2x4 push button organization and
other options have a 5x3 push button organization. Every unit except the 2.8 model, is delivered with a
suitable steel template which makes possible to prepare new cut out by hand after using of hand tools.
There are two orientations possible*: landscape or portrait orientation. This can be specified during
ordering. The user can also change the orientation in the system settings. *Zeus 2.8 is only available in
landscape orientation.
1.1.1 LX Zeus 2.8
This version of Zeus can be installed into any normal 80 mm panel cut out and therefore does not require
an instrument panel upgrade. Display orientation is only landscape.
1.1.2 LX Zeus 4.3
The display diagonal of the system is 4.3 inch and has following outline dimensions:
83x136x52 mm
1.1.3 LX Zeus 5.5
This is the most common used variant and comes with 5.5 inch display. Layout size is:
106x146x52 mm
1.1.4 LX Zeus 7.0
This version size can be fitted in the majority of instrument panels used in modern gliders. The display
size is 7 inch and the unit layout is:
110x190x52 mm
Note!
Pictures used in this manual may slightly differ from the LX Zeus original screens.

LX Zeus v 3.0 25.6.2014

1.1.5 LX Zeus 8.0
This is the biggest LX Zeus model and its display diagonal is 8 inch.
161x218x52 mm
1.1.6 LX Zeus Mobile
LX Zeus Mobile is a derivate from LX Zeus 4.3. The unit uses a 4.3 inch display, the same as by Zeus
4.3. The unit is prepared to be installed as an integral part of the panel, but can be also used as a mobile
device installed on panel by using a gooseneck. A vario unit is also a part of delivery and its default
configuration is a black box solution. An upgrade to color display and the needle is possible at any time.
1.2 Hardware concept
The system is designed to offer flexible solutions of system configurations, so the pilot is able to provide
some kind of custom design. At the back side of the unit there are plenty of connectors which make it
possible to connect (plug and play) a various palette of GPS signal sources, as the unit does not have
integral GPS receiver. Units as Colibri, LX 20, VL and any other GPS source which are capable of
delivering NMEA data at nearly any baud rate, are compatible.
A special plug is provided for Colibri II connection and in that case Colibri II is also powered from Zeus.
Using of Colibri II offers some important benefits for the pilot. The benefits are:
automatic switch on of Colibri II as Zeus is powered on.
automatic power off after Zeus will be switched off and the system is no longer in flying mode; if
flight status is detected, Colibri II will continue logging its own internal battery.
downloading of flights via Zeus USB stick
When two GPS sources are connected at the same time, both signals are combined and losing one of the
GPS sources will not degrade system availability. Colibri II is used as an IGC flight recorder in the case of
an IGC approved solution. In that case a high level of communication is established between Colibri II and
Zeus and the pilot is able to operate the system in the same way as by an integral flight recorder. The
Colibri II unit can operate in portrait and also in landscape orientation. Changing orientation is very easy
and can be done by pilot. See Colibri II user manual for more information.
Commercially available versions:

Rotary switches and push buttons
There are 8 push buttons and two rotary switches on
the front of the unit. Also the rotary switches have a
double push function (short and long press). On one side
there are five push buttons which all have a double push
function (short and long press) and on the other side
there are three push buttons with one push function.
Buttons are labelled and this makes unit manipulation
very easy. (Zeus 2.8 has a 4x4 push button organization.

LX Zeus v 3.0 25.6.2014

Both rotary switches are multifunctional as follows:
Default functions:
audio volume adjustment function
zoom selector
In edit:
zoom: scrolling and press confirmation
volume: bigger steps of scrolling and escape/cancel by pressing
1.2.1 USB and SD port
An A-size USB port is situated on the front panel. The port is exclusively used for data transfer and
firmware updates. The customer can also easily do the firmware updates. The SD port is only used when
a Flarm is connected (Flarm Red Box, Swiss Flarm and optionally Flarm Mini Box). The SD port makes
direct communication with Flarm possible, which means downloading of flights stored in Flarm, uploading
of declaration and also Flarm updating.
1.2.2 Connections
On the back side of the unit there are following connectors:
4x 485 system bus (Zeus 2.8 has 2x 485)*
2x CAN bus**

Voice module
** CAN bus:
Connects Second seat unit
*** Colibri II port:
Makes possible to arrange direct connection of LX Zeus to Colibri II only via cable (special cable
required, is included when purchased together)
**** Flarm port can be also used to connect any other GPS source which has an IGC standard connector.
For instance: Colibri LX 20, VL… If Flarm is connected, two Flarm displays can be connected to the
system by using Display 1 and Display 2 plugs. The SD connector is directly connected to the micro-SD
card reader on the front of the Zeus.
1.3 Software
SW package is completely developed by LX Navigation and is running on Linux operation system. The
logic used kept the well-known LX Navigation philosophy, but some new approaches have been involved.
The SW is continuously developed and upgrades are regularly published. Upgrades of SW can easily be
done by user without requiring any passwords. Contact your dealer to get notified of future updates.

1.4.3 First navigation subpage
First navigation subpage is available after press on SUBP
button and this is valid for all three navigation modes.
The page is divided into two sections. Upper section is
reserved for vertical terrain profile, the lower part shows
APT and TP data. Subpage at TSK shows task’s
statistics by legs.
Vertical terrain profile shows glider position regarding to
the terrain and the airspace. Final glide profile for MC 0
and actual MC is also visualized as a cone.
The terrain is shown in all 3 pages (TP, APT, TSK). The
profile of terrain is bearing to selected TP, APT and with
all TPs on the TSK. The terrain mode also shows the
airspaces in a vertical profile with different colours. With
Zoom knob you can adjust scale.
1.4.4 Second navigation subpage
This page shows 3D terrain data regarding to glider
present position. If the artificial horizon is integrated in the
Zeus, then the second navigation page will be an artificial
horizon (AHRS).
1.5 Rotary Switches
Both rotary switches are multifunctional; their basic functions are audio volume adjustment and zoom
adjustment. The push function on the rotary switches also offers significant help connected with editing
and selection.

audio switch will increase volume by 5%. During input of numbers and letters, rotating will delete wrong
input character and move cursor one position back.
1.6 Automatic jump out of edit
If you get lost in edit, simply don’t touch any command for approximately 15 seconds and the unit will
change back to the last selected menu. This time out in seconds can be set in Setup/User interface/Auto
close inactivity time out.
1.7 Display organisation and management
Additionally to geographic map there are also several extra indicators which make the display information
much more effective than a fixed predetermined solution. How to create custom design is explained in
Setup/Layout. Customization of the display doesn’t require any special tools or a computer; all this can
be done in the Zeus by using the rotary switches and push buttons.
1.7.1 Display organization
LX Zeus display consists of the following:
geographic map
bottom row (navigation boxes)
indicators (header is also an indicator)
1.7.1.1 Indicators

1.7.1.2 Bottom row customization
Bottom row consists of NAV BOXes which are all custom
specific, which means that the pilot is able to create his
own configuration. The procedure is extremely simple
and also executable during flight. The configuration may
differ regarding to mode of operation. The procedure
starts with long press on zoom. After long press the first
NAV BOX becomes a frame. Rotating of the zoom button
can move the position of the frame. As the correct frame
position is reached, pressing zoom again will open a list
of available NAV BOXes.
Available NAV BOXES are:

2.1 Pilot specific settings
The data stored in this part of Setup are pilot specific
data. After pilot selection during booting the data of
individual pilot becomes active. All settings are saved to
the personal saved pilot profile and are active when the
pilot is selected (reserve altitude, logger settings, NAV
BOX line, layout settings, task colours etc…)
2.1.1 Pilots
Pilots name and certain personal data can be stored. All
stored pilot names will be offered during booting.
Selection of one pilot is mandatory. The system offers
one name called as DEFAULT - can be used as a default
pilot. Furthermore plenty of empty positions are offered
and this can be used for pilot names input. Additionally to
the name some additional parameters can be entered,
such as pilot’s weight, default ballast and reserve altitude
–all that will be calculate into final glide. Limiting altitude
means setting of altitude limit that will turn on the altitude
warning alert. You can also save user (pilot) settings to
the USB stick and import user by pressing the buttons:
Import user (VARIO/FLARM) and Save user
(TSK/MOVE). There is also an option to put a password
to each pilot profile, to prevent, that other pilots flying with
the same unit will be able to change settings to the pilot
(this function was especially developed for flying in the
aeroclub). After press on clear password a password will
be removed, also valid for delete user.
2.1.2 Audio settings
This menu defines audio configuration. The audio generator is a part of the vario unit (USB D 60), but
settings are stored in LX Zeus.
Speed command mode:
Defines audio in SC, there are several variants
the most common used setting is both which
means no beep indication by positive deflections.
Speed command volume:
Defines audio volume in SC, may be increased
decreased…
Vario tone:
Defines audio in vario mode, you can adjust
frequencies and also types of audio, use Test
vario after adjustment
Alarm: The audio generator is also capable to generate
some alarms (warnings), combining two frequencies. Set
frequencies and time intervals and use Test to check.
Note!
All settings active at the moment of
new pilot creation under “Pilot” will be
adopted.
Use Test vario option to play the audio variant.
It is important to change over to SC before test;
otherwise vario audio variant will be
reproduced.
The frequencies set are also valid for SC audio.
